Abstract
The Secretary of Education (or other appropriate authority) has not determined that using manipulatives is . either a sufficient or a' necessary condition for meaningful learning. (Baroody, 1989, p. 4) Statements extolling the virtues of manipulatives (concrete materials) for the learning of mathematics abound in curriculum documents, research literature and, even, textbook series. ... Concrete materials are often seen by teachers as the basis for mathematical learning. But is this a reasonable view? In this paper, through a review of the literature concerning the use of concrete materials, we build up an historical view of the place of these materials in the learning and teaching of mathematics. Examples of situations in which the use of concrete materials has constrained children's mathematics learning are discussed along with the notion that materials introduce 'reality'to children's mathematical learning. Current research on children's thinking in the social and cultural contexts of their mathematics learning is used to help explain ways in which concrete materials can help and hinder this learning and how the very notion of manipulative might be f/!xpanded beyond concrete materials.
